Templates. Structures of templates: Templates from ten well-clustered samples before (left) and after (right) stimulation (projection into three dimensions, ZAP70 is not shown). In a template, each meta-cluster is indicated with a distinct color; four meta-clusters are present in each template. Corresponding meta-clusters across templates are plotted with the same color. Naive CD4+CD45RAhigh T cell population is colored in blue, and Memory CD4+CD45RAlow T cell population is colored in red. Details of the clusters in each meta-cluster are shown in Table 1.
